Description

Technical Field

[0001] This utility model relates to the field of tire technology, and more specifically, to a tire tread structure and a tire having the same. Background Technology

[0002] Currently, truck tires on the market do not adequately consider tire deformation under different loads and road conditions, easily leading to abnormal tire wear, which in turn affects tire lifespan and safety. In particular, the tire shoulder area bears significant pressure during steering and heavy loads, and existing tire shoulder designs do not fully account for this factor, resulting in insufficient heat dissipation in the shoulder area and accelerated wear. At the same time, truck tires struggle to provide sufficient grip on wet or snowy roads.

[0003] In summary, existing truck tire technologies cannot simultaneously achieve wear resistance, good traction, and strong grip, making it difficult to meet users' needs. Utility Model Content

Meanwhile, the irregular groove angles and distribution help reduce the noise generated when the tire rolls, thereby improving driving comfort. Furthermore, the steel plates can enhance the rigidity of the tread blocks, further reducing the rolling resistance caused by tread block deformation, and providing additional traction under specific conditions. This solves the problem that existing tires cannot simultaneously achieve wear resistance, good driving performance, and strong grip. Attached Figure Description

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0030] In this utility model, unless otherwise stated, directional terms such as "upper" and "lower" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" are generally used in relation to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0031] To address the problem that existing tires cannot simultaneously achieve wear resistance, good traction, and strong grip, this application provides a tire tread structure and a tire having the same structure.

[0032] like Figure 1As shown, the tire tread structure includes two first longitudinal grooves 10, two second longitudinal grooves 20, a first lateral groove group 30, and two second lateral groove groups 40. The two second longitudinal grooves 20 are located between the two first longitudinal grooves 10 and are connected by the first lateral groove groups 30. The first lateral groove group 30 includes a plurality of first grooves 31 spaced apart along the circumference of the tire. At least one first groove 31 includes a first groove segment 311 and a second groove segment 312 that are connected to each other. The extending directions of the first groove segment 311 and the second groove segment 312 are set at an angle A and satisfy: 150°≤A≤175°. Two second transverse groove groups 40 are arranged in a one-to-one correspondence with two first longitudinal grooves 10. Each first longitudinal groove 10 is connected to the adjacent second longitudinal groove 20 through its corresponding second transverse groove group 40. Each second transverse groove group 40 includes a plurality of second grooves 41 arranged at intervals along the circumference of the tire. At least a portion of at least one second groove 41 is a bent groove segment, and the bending angle B of the bent groove segment satisfies: 140°≤B≤165°. Two adjacent first grooves 31 and two second longitudinal grooves 20 surround to form a first tread block 50. Two adjacent second grooves 41, one first longitudinal groove 10, and one second longitudinal groove 20 surround to form a second tread block 60. Steel plates 70 are provided on both the first tread block 50 and the second tread block 60.

[0033] By applying the technical solution of this embodiment, through the included angle A formed between the first groove segment 311 and the second groove segment 312, and the bent groove segment design of the second groove 41 in the second lateral groove group 40, the tire can form multi-directional grip when in contact with the ground. Especially on wet and slippery roads, the above-mentioned groove design with special angles can effectively drain water and increase the contact area between the tire and the road surface, thereby significantly improving wet handling stability and grip performance. At the same time, the special layout of the first lateral groove group 30 and the second lateral groove group 40, as well as the steel plate 70 set on the tread block, can not only ensure the tire's good performance under different road conditions, but also disperse the impact force generated when the tire touches the ground through the bending and included angle design, reducing rolling resistance. Meanwhile, the irregular groove angle and distribution help reduce the noise generated when the tire rolls, thereby improving driving comfort. Furthermore, the steel plate 70 can enhance the rigidity of the tread block, further reducing the rolling resistance caused by the deformation of the tread block, and providing additional traction under specific conditions, thus solving the problem that tires in the prior art cannot simultaneously achieve wear resistance, good driving performance, and strong grip.

[0034] In this embodiment, the included angle A is 160°. It should be noted that the value of the included angle A is not limited to this and can be adjusted according to the working conditions and usage requirements. Optionally, the included angle A is 155°, or 158°, or 165°, or 168°, or 170°.

[0035] In this embodiment, the included angle B is 150°. It should be noted that the value of the included angle B is not limited to this and can be adjusted according to the working conditions and usage requirements. Optionally, the included angle B is 145°, or 148°, or 155°, or 158°, or 160°.

[0036] In other embodiments not shown in the accompanying drawings, only the first patterned block 50 is provided with a steel sheet 70.

[0037] In other embodiments not shown in the accompanying drawings, only the second patterned block 60 is provided with a steel sheet 70.

[0038] like Figure 1 As shown, the tire tread structure also includes two third lateral groove groups 80. The two third lateral groove groups 80 are arranged in a one-to-one correspondence with the two first longitudinal grooves 10, and each third lateral groove group 80 is connected to its corresponding first longitudinal groove 10. Each third lateral groove group 80 includes a plurality of third grooves 81 spaced apart along the circumference of the tire. In each third lateral groove group 80, the first longitudinal groove 10 corresponding to that third lateral groove group 80 and two adjacent third grooves 81 in that third lateral groove group 80 surround each other to form a third tread block 90. ​​At least one third groove 81 is provided with a reinforcing rib 100, and the surface of the tire tread structure protrudes beyond the reinforcing rib 100. Thus, by providing the reinforcing rib 100 in the third groove 81 of the third lateral groove group 80, the reinforcing rib 100 can provide additional support force when the tire rotates, enhancing the rigidity of the third tread block 90. At the same time, the above design can not only effectively disperse the pressure when the tire touches the ground and reduce the local stress concentration of the tread blocks, thereby reducing the uneven wear phenomenon that occurs during the tire's operation, especially when the load is uneven, and extending the tire's service life, but also increase the tire's resistance to abnormal wear, making the overall deformation of the tread blocks more uniform, thereby enhancing the tire's ride comfort.

[0039] In this embodiment, the reinforcing rib 100 not only increases the rigidity of the tire, but can also act as a grip edge in certain situations, especially on wet or icy roads. Due to the presence of the reinforcing rib 100, a more stable tread block structure can be formed when the tire contacts the ground, increasing the effective contact area between the tire and the ground, improving the tire's grip in wet and icy conditions, thereby enhancing the vehicle's handling stability and safety.

[0040] Optionally, along the circumference of the tire, each first longitudinal groove 10 includes a plurality of sequentially connected first longitudinal groove groups. Each first longitudinal groove group includes a third groove segment 11 and a fourth groove segment 12 that are interconnected. The third groove segment 11 and / or the fourth groove segment 12 are inclined relative to the center plane CS of the tire tread structure, and the third groove segment 11 and the fourth groove segment 12 are set at an obtuse angle C. Specifically, the angle between the third groove segment 11 and the center plane CS is greater than or equal to 5° and less than or equal to 15°; and / or, the angle between the fourth groove segment 12 and the center plane CS is greater than or equal to 5° and less than or equal to 15°. Thus, the inclined arrangement of the third groove segment 11 and the fourth groove segment 12 in the first longitudinal groove 10 relative to the tire center plane CS, and the obtuse angle C formed between them, can significantly improve the tire's water drainage efficiency. When the tire rotates, the above structure can more effectively guide water out from the gaps between the tread blocks, avoiding the water film effect, thereby providing stronger grip on wet and slippery roads and enhancing the vehicle's handling stability and braking performance. Meanwhile, by precisely controlling the angle between the third groove segment 11 and the fourth groove segment 12 and the center plane CS, making it between 5° and 15°, it helps to optimize the contact shape of the tire tread, reduce the deformation of the tire when in contact with the ground, and thus reduce rolling resistance.

[0041] like Figure 1 As shown, each first longitudinal groove 10 includes multiple sequentially connected first longitudinal groove groups. Each first longitudinal groove group includes a third groove segment 11 and a fourth groove segment 12 that are interconnected. Both the third groove segment 11 and the fourth groove segment 12 are inclined relative to the center plane CS of the tire tread structure, and the third groove segment 11 and the fourth groove segment 12 are set at an obtuse angle C. The included angle between the third groove segment 11 and the center plane CS is 10°, and the included angle between the fourth groove segment 12 and the center plane CS is 10°.

[0042] It should be noted that the angle between the third groove segment 11 and the center plane CS is not limited to this value and can be adjusted according to working conditions and usage requirements. Optionally, the angle between the third groove segment 11 and the center plane CS is 8° or 12°.

[0043] It should be noted that the angle between the fourth groove segment 12 and the center plane CS is not limited to this value and can be adjusted according to working conditions and usage requirements. Optionally, the angle between the fourth groove segment 12 and the center plane CS is 8° or 12°.

[0044] Optionally, along the circumference of the tire, each second longitudinal groove 20 includes a plurality of sequentially connected second longitudinal groove groups. Each second longitudinal groove group includes a fifth groove segment 21 and a sixth groove segment 22 that are interconnected. The fifth groove segment 21 and / or the sixth groove segment 22 are inclined relative to the center plane CS of the tire tread structure, and the fifth groove segment 21 and the sixth groove segment 22 are set at an obtuse angle D. The angle value of the obtuse angle D is less than or equal to the angle value of the obtuse angle C. The angle between the fifth groove segment 21 and the center plane CS is greater than or equal to 5° and less than or equal to 15°; and / or the angle between the sixth groove segment 22 and the center plane CS is greater than or equal to 5° and less than or equal to 15°. In this way, the inclined design of the fifth groove segment 21 and the sixth groove segment 22 in the second longitudinal groove 20, and the obtuse angle D formed between them, can optimize the tire's contact patch characteristics, enabling the tire to respond more quickly to the driver's operation during steering and improving handling precision. Meanwhile, the inclination angles of the fifth groove segment 21 and the sixth groove segment 22 relative to the center plane CS are set in the range of 5° to 15°, which helps to quickly remove water or slush when the tire comes into contact with wet or snowy road surfaces through the guiding effect of the groove segments, preventing the tire from slipping. The setting of the obtuse angle D (its angle value is less than or equal to the angle value of the obtuse angle C) ensures that the tire maintains good grip when moving laterally and longitudinally, thereby improving the vehicle's driving performance and safety under various adverse weather conditions.

[0045] like Figure 1 As shown, along the circumference of the tire, each second longitudinal groove 20 includes multiple sequentially connected second longitudinal groove groups. Each second longitudinal groove group includes a fifth groove segment 21 and a sixth groove segment 22 that are interconnected. Both the fifth groove segment 21 and the sixth groove segment 22 are inclined relative to the center plane CS of the tire tread structure, and the fifth groove segment 21 and the sixth groove segment 22 are set at an obtuse angle D; the angle value of the obtuse angle D is less than or equal to the angle value of the obtuse angle C. Specifically, the angle between the fifth groove segment 21 and the center plane CS is 10°; and / or, the angle between the sixth groove segment 22 and the center plane CS is 10°.

[0046] It should be noted that the angle between the fifth groove segment 21 and the center plane CS is not limited to this value and can be adjusted according to working conditions and usage requirements. Optionally, the angle between the fifth groove segment 21 and the center plane CS is 8° or 12°.

[0047] It should be noted that the angle between the sixth groove segment 22 and the center plane CS is not limited to this value and can be adjusted according to working conditions and usage requirements. Optionally, the angle between the sixth groove segment 22 and the center plane CS is 8° or 12°.

[0048] Optionally, the bending groove segment includes a seventh groove segment 411, an eighth groove segment 412, and a ninth groove segment 413 that are bent sequentially and connected. The seventh groove segment 411 and the ninth groove segment 413 are arranged parallel to each other. The seventh groove segment 411 is connected to the first longitudinal groove 10, and the ninth groove segment 413 is connected to the second longitudinal groove 20. The seventh groove segment 411 and the eighth groove segment 412 are arranged at an angle E, and the angle E is less than the angle A. And / or, the third groove 81 and the second groove 41 are located on both sides of the first longitudinal groove 10 and are staggered. Thus, the design of the seventh groove segment 411, the eighth groove segment 412, and the ninth groove segment 413 in the bending groove section, especially the parallel relationship between the seventh groove segment 411 and the ninth groove segment 413, and the angle E formed with the eighth groove segment 412 that is smaller than the included angle A, not only provides a more stable support point when the tire is turning, improving the vehicle's steering response, but the bending groove segment also helps to break the water film on wet and slippery roads, enhancing the direct contact between the tire and the road surface, improving wet grip, and increasing driving safety. At the same time, the third groove 81 and the second groove 41 are staggered and located on both sides of the first longitudinal groove 10. This layout helps to distribute the stress points when the tire is rolling, reducing local stress concentration, thereby reducing the possibility of uneven tire wear.

[0049] like Figure 1 As shown, the bending groove section exhibits a "Z" shaped trend, which increases the driving force in multiple aspects and has a beneficial effect on reducing rolling resistance. The third groove 81 and the second groove 41 are located on both sides of the first longitudinal groove 10 and are staggered, thereby ensuring the uniformity of the overall rigidity of the third pattern block 90 and the second pattern block 60.

[0050] Optionally, the width L1 of the first longitudinal groove 10 is greater than or equal to 10 mm and less than or equal to 15 mm, the width L2 of the second longitudinal groove 20 is greater than or equal to 5 mm and less than or equal to 8 mm, and the width L1 of the first longitudinal groove 10 is greater than the width L2 of the second longitudinal groove 20; and / or, the width L3 of at least one third groove 81 is greater than the width L4 of the first groove 31; and / or, the width L3 of at least one third groove 81 is greater than the width L5 of the second groove 41. Thus, the first longitudinal groove 10 has a larger width L1 (10 mm to 15 mm), which is wider than the width L2 of the second longitudinal groove 20 (5 mm to 8 mm), thereby ensuring that the tire quickly drains water on wet surfaces, preventing the formation of a water film, and thus providing higher grip and a shorter braking distance when driving in rain or snow, significantly improving driving safety. Meanwhile, the groove width L3 of the third groove 81 is wider than the groove width L4 of the first groove 31 or the groove width L5 of the second groove 41. This differentiated groove width design helps to form a more effective distribution of tread block rigidity when the tire contacts the ground, reducing excessive deformation of the tread blocks and thus improving the tire's wear resistance. The larger groove width of the third groove 81 also helps to improve the tire's handling stability under complex road conditions, especially on sandy or muddy roads where extra grip is required.

[0051] like Figure 1 As shown, the width L1 of the first longitudinal groove 10 is 12mm, and the width L2 of the second longitudinal groove 20 is 6mm. The width L1 of the first longitudinal groove 10 is greater than the width L2 of the second longitudinal groove 20. The width L3 of each third groove 81 is greater than the width L4 of the first groove 31, and the width L3 of each third groove 81 is greater than the width L5 of the second groove 41.

[0052] It should be noted that the value of the groove width L1 of the first longitudinal groove 10 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, the groove width L1 of the first longitudinal groove 10 is 11mm, 13mm, or 14mm.

[0053] It should be noted that the value of the groove width L2 of the second longitudinal groove 20 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, the groove width L2 of the second longitudinal groove 20 is 7mm.

[0054] Optionally, the ratio of the width of the second tread block 60 to the width of the first tread block 50 is greater than or equal to 0.9 and less than or equal to 1.15; and / or, the ratio of the width of the third tread block 90 to the width of the first tread block 50 is greater than or equal to 1.00 and less than or equal to 1.35. Thus, by setting the ratio of the width of the second tread block 60 to the width of the first tread block 50 to be between 0.9 and 1.15, and the ratio of the width of the third tread block 90 to the width of the first tread block 50 to be between 1.00 and 1.35, the aforementioned precise width ratios balance the rigidity distribution of the tire in different areas. During tire use, this design helps reduce localized wear, ensuring even wear across all parts of the tire and extending its overall service life. Simultaneously, this setting optimizes tire handling stability and comfort: the appropriate ratio of tread block widths not only affects tire wear resistance but also has a significant impact on tire handling performance and ride comfort.

[0055] In this embodiment, the width ratio of the second tread block 60 to the width of the first tread block 50 is 1, and the width ratio of the third tread block 90 to the width of the first tread block 50 is 1.20. This allows the tread blocks with appropriately proportioned widths to form a stable contact patch when the tire contacts the ground, improving the tire's handling stability under various road conditions. Simultaneously, this design reduces tire vibration at high speeds, enhancing vehicle ride smoothness and comfort.

[0056] It should be noted that the ratio of the width of the second patterned block 60 to the width of the first patterned block 50 is not limited to this value and can be adjusted according to working conditions and usage requirements. Optionally, the ratio of the width of the second patterned block 60 to the width of the first patterned block 50 is 0.95, 1.05, or 1.1.

[0057] It should be noted that the ratio of the width of the third patterned block 90 to the width of the first patterned block 50 is not limited to this value and can be adjusted according to working conditions and usage requirements. Optionally, the ratio of the width of the third patterned block 90 to the width of the first patterned block 50 is 1.05, 1.10, 1.15, 1.25, or 1.30.

[0058] Optionally, the width L4 of the first groove 31 is greater than or equal to 3.5 mm and less than or equal to 7.0 mm; and / or, the width L5 of the second groove 41 is greater than or equal to 3.5 mm and less than or equal to 7.0 mm; and / or, the width L3 of the third groove 81 is greater than or equal to 7.0 mm and less than or equal to 12.0 mm; and / or, the third groove 81 includes a tenth groove segment 811 and an eleventh groove segment 812 that are interconnected, the included angle between the tenth groove segment 811 and the eleventh groove segment 812 is greater than or equal to 65° and less than or equal to 80°, and the eleventh groove segment 812 is connected to the first longitudinal groove 10 through the tenth groove segment 811. Thus, the groove widths L4 and L5 of the first groove 31 and the second groove 41 are designed to be between 3.5mm and 7.0mm. This size range effectively improves the tire's water drainage capacity and snow removal efficiency. Especially on wet or snowy roads, the narrower groove width helps to form sufficient tread block rigidity when the tire rolls, ensuring the tire's wear resistance and dry grip. Meanwhile, the groove width L3 of the third groove 81 is between 7.0mm and 12.0mm, which is wider than the groove widths of the first groove 31 and the second groove 41. This helps to distribute stress when the tire contacts the ground, reduce localized wear of the tread blocks, and improve the tire's uniform wear performance. The angle formed between the tenth groove segment 811 and the eleventh groove segment 812 is between 65° and 80°. This angle design optimizes the tire's contact patch shape, reduces vehicle vibration during high-speed driving and cornering, improves driving comfort, provides additional grip during lateral and longitudinal vehicle movement, and enhances handling stability and driving safety.

[0059] like Figure 1 As shown, the width L4 of the first groove 31 is 5.0 mm, the width L5 of the second groove 41 is 5.0 mm, and the width L3 of the third groove 81 is 10.0 mm. The third groove 81 includes a tenth groove segment 811 and an eleventh groove segment 812 that are interconnected. The angle between the tenth groove segment 811 and the eleventh groove segment 812 is 70°, and the eleventh groove segment 812 is connected to the first longitudinal groove 10 through the tenth groove segment 811.

[0060] It should be noted that the value of the groove width L4 of the first groove 31 is not limited to this and can be adjusted according to the working conditions and usage requirements. Optionally, the groove width L4 of the first groove 31 is 3.8mm, or 4.0mm, or 4.5mm, or 4.8mm, or 5.5mm, or 5.8mm, or 6.0mm, or 6.5mm, or 6.8mm.

[0061] It should be noted that the value of the groove width L5 of the second groove 41 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, the groove width L5 of the second groove 41 is 3.8mm, or 4.0mm, or 4.5mm, or 4.8mm, or 5.5mm, or 5.8mm, or 6.0mm, or 6.5mm, or 6.8mm.

[0062] It should be noted that the value of the groove width L3 of the third groove 81 is not limited to this and can be adjusted according to the working conditions and usage requirements. Optionally, the groove width L3 of the third groove 81 is 7.5mm, or 8.0mm, or 8.5mm, or 9.0mm, or 9.5mm, or 10.5mm, or 11mm, or 11.5mm.

[0063] It should be noted that the angle between the tenth slot segment 811 and the eleventh slot segment 812 is not limited to this value and can be adjusted according to working conditions and usage requirements. Optionally, the angle between the tenth slot segment 811 and the eleventh slot segment 812 can be 68°, 75°, or 78°.

[0064] Optionally, there are multiple steel plates 70, including a first steel plate 71 and a second steel plate 72. The first steel plate 71 is disposed on the first patterned block 50, with an insertion depth of h1 within the first patterned block 50, and the groove depth of the second longitudinal groove 20 is h2, satisfying: 2mm ≤ h2 - h1 ≤ 8mm. And / or, the second steel plate 72 is disposed on the second patterned block 60, with an insertion depth of h3 within the second patterned block 60, and the groove depth of the first longitudinal groove 10 is h4, satisfying: 2mm ≤ h4 - h3 ≤ 8mm. Thus, the depth design of the first steel plate 71 and the second steel plate 72 respectively satisfies the difference in longitudinal groove depth between the areas where the first patterned block 50 and the second patterned block 60 are located between 2mm and 8mm. This design ensures that on icy and snowy roads, the steel plates can penetrate deep into the ground, providing additional grip. Therefore, when driving on snow or ice, the vehicle can obtain better traction and braking performance, significantly improving the safety of winter driving. Meanwhile, the depth difference between the steel sheet and the tire tread block is controlled within a reasonable range, which can effectively prevent the steel sheet from wearing out excessively when driving on normal roads. It ensures that when encountering road gravel, the steel sheet can actively bounce off the gravel stuck in the groove through elastic deformation, reducing the "stone trapping" phenomenon, protecting the tire from damage caused by stone impact, and extending the tire's service life.

[0065] like Figure 1 As shown, there are multiple steel sheets 70, including a first steel sheet 71 and a second steel sheet 72. The first steel sheet 71 is disposed on the first patterned block 50, and the depth of insertion of the first steel sheet 71 into the first patterned block 50 is h1. The groove depth of the second longitudinal groove 20 is h2, satisfying: h2 - h1 = 5 mm. The second steel sheet 72 is disposed on the second patterned block 60, and the depth of insertion of the second steel sheet 72 into the second patterned block 60 is h3. The groove depth of the first longitudinal groove 10 is h4, satisfying: h4 - h3 = 5 mm.

[0066] It should be noted that the values ​​of h2-h1 are not limited to these and can be adjusted according to working conditions and usage requirements. Optionally, h2-h1 = 3mm, or h2-h1 = 4mm, or h2-h1 = 6mm, or h2-h1 = 7mm.

[0067] It should be noted that the values ​​of h4-h3 are not limited to these and can be adjusted according to working conditions and usage requirements. Optionally, h4-h3 = 3mm, or h4-h3 = 4mm, or h4-h3 = 6mm, or h4-h3 = 7mm.

[0068] Optionally, three different tread pitches are provided along the circumference of the tire tread structure, namely a first tread pitch PA, a second tread pitch PB, and a third tread pitch PC, wherein the pitch ratio of the first tread pitch PA to the second tread pitch PB is greater than or equal to 1.05 and less than or equal to 1.21, and the pitch ratio of the second tread pitch PB to the third tread pitch PC is greater than or equal to 1.0 and less than or equal to 1.15; and / or, the tenth groove segment 811 has a connecting slot communicating with the first longitudinal groove 10, at least a portion of the groove wall of the connecting slot being an inclined surface 813, the inclined surface 813 being inclined toward the side opposite to the connecting slot; and / or, the third tread block 90 is provided with a tread pattern. In this way, the first tread pitch PA, the second tread pitch PB, and the third tread pitch PC along the tire tread adopt a variable pitch design. That is, the pitch ratio of the first tread pitch PA to the second tread pitch PB is between 1.05 and 1.21, and the pitch ratio of the second tread pitch PB to the third tread pitch PC is between 1.0 and 1.15. The arrangement of these unequal pitches can effectively disperse the sound waves generated when the tire rolls, reduce the superposition of specific frequency sounds, thereby reducing tire noise and improving the quietness of the vehicle interior and the comfort of the driver. At the same time, the connecting groove of the tenth groove segment 811 is set with an inclined surface 813. The inclined surface 813 is inclined to the side away from the connecting groove, which facilitates the rapid discharge of water when the tire rolls. Especially under wet and slippery road conditions, it can effectively reduce the formation of water film and improve wet grip. Moreover, the guiding effect of the inclined surface 813 helps gravel and other foreign objects to fall naturally from the groove, avoiding the decline in tire performance caused by foreign objects getting stuck, and maintaining good tire grip and wear resistance.

[0069] This application also provides a tire (not shown) including the tire tread structure described above.

[0070] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0071] Through the angle A formed between the first and second groove segments and the bent groove design of the second groove in the second lateral groove group, the tire can form multi-directional grip when in contact with the ground. Especially on wet and slippery roads, the above-mentioned special angle groove design can effectively drain water and increase the contact area between the tire and the road surface, thereby significantly improving wet handling stability and grip performance. At the same time, the special layout of the first and second lateral groove groups, as well as the steel plates set on the tread blocks, not only ensure the tire's good performance under different road conditions, but also disperse the impact force generated when the tire touches the ground through the bending and angle design, reducing rolling resistance. Meanwhile, the irregular groove angles and distribution help reduce the noise generated when the tire rolls, thereby improving driving comfort. Furthermore, the steel plates can enhance the rigidity of the tread blocks, further reducing the rolling resistance caused by tread block deformation, and providing additional traction under certain conditions. This solves the problem that existing tires cannot simultaneously achieve wear resistance, good driving performance, and strong grip.
